The only time I ever shut up my bitch of a mother bout politics was shortly after Obama won and she was complaining about something stupid.
"What happened to, 'It's un-American to complain about the Commander-in-Chief?' "
"You complained about Bush all the time!"
"Because I believe it's my civic responsibility to hold my leaders accountable. But you said over and over that was wrong. Did you change your mind, or is it only un-American to criticize the president you like?"
She was (probably still is) a malignant narcissist, so I paid for that, but the satisfaction of seeing her grasp for straws was worth it.
